Back in December 2018 I made a prepayment order for a modem board (Raspberri Pi HAT) from this business. They indicated the boards were on order and would be shipped by the end of January 2019. I contacted them last week via email and asked what the current status of this item was. They have not responded. I fear they are not going to deliver and will not refund my $ 179.00. Until I hear from them I suggest no other hams places an order with a prepayment to this business.
